* gdb.base/attach-pie-misread.exp: Load prelink-support.exp. Replace build_executable by build_executable_own_libs. Replace "prelink -R" execution by a call of prelink_yes. Comment why "prelink -r" needs no change. * gdb.base/break-interp.exp: Load prelink-support.exp. Rename calls of copy to file_copy. Move setting opts --dynamic-linker and -rpath, mkdir $dir and ldd its parsing and copying to lib/prelink-support.exp. Replace build_executable by build_executable_own_libs's function build_executable_own_libs. (prelinkNO): Create new stub to call prelink_no. (prelinkYES): Create new stub to call prelink_yes. (test_attach): Rename calls of copy to file_copy. (section_get, prelinkNO_run, prelinkNO, prelinkYES, symlink_resolve) (copy): Move to ... * lib/prelink-support.exp: ... a new file. Rename prelinkNO to prelink_no, prelinkYES to prelink_yes, copy to file_copy. * gdb.base/prelink.exp: Disable testcase also for is_remote and skip_shlib_tests. Load prelink-support.exp. Replace gdb_compile with special flags by gdb_compile_shlib. Replace second gdb_compile by build_executable_own_libs. Replace "prelink -R" execution by a call of prelink_yes. Replace "prelink -u" and second "prelink -R" execution by a second call of prelink_yes. Replace restart commands by clean_restart. (prelink): Rename to ... (seen displacement message): ... this test. Extend its expectation strictness.
